Sheet Metal Fabrication Process

What is Metal Fabrication?

Hi! Today we’re going to be talking about what metal fabrication is.

We’ve been going all over the place with these blogs, so I think it’s time

we head to the basics.


Metal Fabrication: Definition

Metal fabrication is the process of making structures and formations

from raw metal. Fabrication techniques such as cutting, drilling, welding,

etc., are used in the overall method of manufacturing metal products.

Basically, sheet metal fabrication is when you create a metal formation

using a broad range of techniques.

Usually, sheets of any type of metal are merged to create a larger final

product. To combine these smaller pieces, processes like welding are

used to make a high-quality finished product that creates various

products that come in all shapes and sizes.

What do sheet metal fabricators do?

Whether designing or assembling the product, a metal fabricator will

specialize in at least one of the techniques involved in the fabrication


Sheet Metal Fabrication Techniques

Every project and order are different, but usually they use the following

techniques in the process.


Different companies have different ways they design and different

software. However, at Aston Precision, we always ask customers for

their preferences before we begin. SolidWorks is the software we use to

design. It is a very effective and helpful system.


When the design has been perfected, it is into program that can be

understood by machinery that creates products. Parts are drawn and

then put into 2D form onto a metal sheet, making sure that material

application is maximized.


When the machine has been set to work, the laser cutting process

begins. Lasers are one of the most precise ways to cut sheet metal

material, as they follow the programmed design and cut through the

material with ease.


Many factors need specific perforations or forms such as ribs, louvres, or

countersinks. For this, a CNC Turret punching machine uses specific tools to

“hit” the metal sheet and either perforate or shape it in precise ways.


The bending process, known I the industry and CNC folding, is a

practice that can be completed by a variety of different machines, like a

manual press brake, an automated panel bending machine or robotic

bend cell. Each machine forms the part by clamping the sheet metal

between a top tool and die, applying pressure to gain the anticipated



There are many types of welding techniques that can be done when

working with sheet metal. This includes, MIG welding, TIG welding, spot

welding, projection welding, etc.


The assembly step can differentiate depending on the difficulty of the

final product and can go from easy weld assemblies to complex

electrical integrations including wiring looms, PAT testing and hardware

installation. Some assemblies have a necessity of insertion which is the

process of pressing a stud, nuts, or other components to secure the

product together.

Powder Coating

The final step in most scenarios, is powder coating. The powder coating

process is a practice of applying and electrostatic powder to a charged

metal component before curing at heat to create a durable coating.
